TEMPORARY BONDING CONNECTION DURING ARRAY MAINTENANCE
When removing modules for replacement or system maintenance, any module left in place that is secured
with a bonding Midclamp will be properly grounded. If a module adjacent to the end module of a row is
removed or if any other maintenance condition leaves a module without a bonding mid clamp, a temporary
bonding connection must be installed as shown
• Attach Ilsco SGB4 to wall of rail
• Attach Ilsco SGB4 to module frame
• Install solid copper wire jumper to Ilsco lugs

ELECTRICAL CONSIDERATIONS
SOLARMOUNT is intended to be used with PV
modules that have a system voltage less than or
equal to 1000 VDC. For standard system grounding
a minimum 10AWG, 105°C copper grounding
conductor should be used to ground a 1000 VDC
system, according to the National Electric Code
(NEC). It is the installer’s responsibility to check local
codes, which may vary. See below for interconnection
information.
INTERCONNECTION INFORMATION
There is no size limit on how many SOLARMOUNT
& PV modules can be mechanically interconnected
for any given conguration, provided that the
installation meets the requirements of applicable
building and re codes.
GROUNDING NOTES
The installation must be conducted in accordance
with the National Electric Code (NEC) and the
authority having jurisdiction. Please refer to these
resources in your location for required grounding lug
quantities specic to your project.
The grounding / bonding components may overhang
parts of the array so care must be made when
walking around the array to avoid damage.
Conductor fastener torque values depend on
conductor size. See product data sheets for correct
torque values.
REQUIRED ONLY FOR TEMPORARY
BONDING DURING ARRAY MAINTENANCE
